Title: Photographic roll-film camera
IPC: G03B19/04
Filed: 1934-10-30
Abstract: 446,519. Photographic roll - film cameras. I. G. FARBENINDUSTRIE AKT.- GES., Frankfort-on-Main, Germany. Oct. 30, 1934, No. 31104. Convention date, Nov. 9, 1933. [Class 98 (i)] A photographic roll-film camera has a device f or guiding an unperforated new film into its operative position in the camera which also serves for advancing the unperforated film into successive positions for fresh exposures and is arranged, when the camera lid is closed to engage automatically with the end of the film allowed to project from the paying- out box and remains in engagement with the unperforated film over the height of a whole picture once the film has been fully engaged by the device. As shown, in the rear wall 1 of the camera are mounted two pairs of sprockets 3, 4 over each pair of which passes a chain 6 provided with teeth 5 and moved in the direction of the arrow E by the pawl 7 pressed against the chain by a spring 10. The pawl 7 is pivoted to a plate 12 carrying a button 13. The advancing mechanism has a return spring 11. Inclined guide surfaces on a guide plate 16 cause the teeth 5 to engage the film and move it in the direction of the arrow F. When the camera is closed the teeth 5 engage the end of the film projecting from the end of the paying-out box, and the film is fed automatically into the take-up box, where it winds up on itself. By operating the button 13 once or twice, after the insertion or removal of a mask, pictures of two different sizes may be obtained.

Patent GB-892912-A (GB)
Title: Improvements in or relating to yarn tension control devices
IPC: B65H59/14
Filed: 1958-10-02
Abstract: 892,912. Yarn trimming. STANIER, H. Jan. 1, 1960 [Oct. 2, 1958], No. 31440/58. Classes 120(2) and 142(1) A yarn tension control device comprises a disc tension means followed, with respect to the direction of the yarn travel, by a yarn trapping means which normally provides a free passage for the yarn but traps the yarn when the tension is relieved, and means for changing the position of the disc tension means so that the path and therefore the tension of the yarn may be varied. As shown in Fig. 1 the base plate 11 of the device is fixed in a horizontal plane to a side member 13 of the creel and carries a ceramic guide 14 in the centre of an anti-ballooning disc 12 at a suitable ballooning distance from the package 50. The yarn is withdrawn over the end of the package, passes through the trapping means 28 and through a movable guide 20 intermediate fixed guides 18, 19. Guide 20 rotates about a pivot 23 (Fig. 3) in a stiff wire arm 21 under the influence of a counterweight 22 so arranged that the guide tends to pull the yarn out of a straight line path between guides 18 and 19. When the yarn runs in a straight line path from 18 to 19 the counterweight acting as a cam raises a plunger 26 which lifts the upper disc 32 of the trapping means so that the yarn is unimpeded. The trapping means comprise a fixed post 27 carrying lower and upper discs 30, 32 which are freely rotatable, the upper disc being adapted to be lifted as described above; a screw provides means for varying the instant at which the upper disc is raised. Between the guide 14 and the trapping means the four similar disc tensioners are adjustably mounted in slots 36 and 47. Each device (Fig. 5) comprises a guide post 40 which has upper and lower, freely rotatable discs 41, 42 and is adjustably fixed to the base 11 by a bolt 39 engaging a nut 38. The yarn is arranged to pass through or about one or more of the tensioners 41, 44, 48, 49 in any desired path to give the required tension; further adjustment in the yarn may be obtained by altering the positions of the tensioners, by altering the upper discs for discs of different weight or by placing two or more upper discs on the tensioner. When the yarn slackens, e.g. when a package empties, the guide 20 falls away and the counterweight 25 engages an electrical contact so as to make, or break, a circuit which in turn stops the machine to which the yarn is passing; at the same time the device 28 traps the yarn which is thus held taut between the using machine and the device. The device is threaded by a needle or hook, the tensioner 41 having been shifted to either end of its slot. Since the discs in the tensioners and trapping means are freely rotatable they are self cleaning. Specifications 795,800 and 820,481 are referred to.

Abstract: 281,296. Schauer, A., and Wolff, E., (trading as Evolutor Ing. A. Schauer & E. Wolff Handelsges.). Nov. 23, 1926, [Convention date]. No Patent granted (Sealing fee not paid]. Variable-speed and reversing friction gearing. -Friction gearing is rendered operative by closing a tightening ring such as 7, Fig. 7, upon a flexible tread member 5 which thus engages frictionally with rollers 4. In another form, coned tightening rings 13, 13', Fig. 5, are drawn together to constrict a spring tread 6 upon rollers 4<11>. These treads are flat spiral bands. A change-speed and reversing gear is shown. A driving-shaft I carries secured thereto friction sun gears 3, 3<1> and a toothed clutch disc 11. A sleeve 8 loose on the shaft carries planet rollers 4 of the first train, like rollers 4' of the second train, the central gear 3<11> of the reversing train, and a toothed clutch disc 12. The rollers 4<11> of the reversing train are carried by a fixed web 9. An internally-toothed clutch 10 is feathered on a driven shaft 2. To effect a one-toone drive, the clutch 10 is engaged with disc 11. First reducer speed is effected by tightening a screw 19, Fig. 1, which causes the sleeve 8 to be driven. The clutch 10 is moved into engagement with disc 12. The third speed is effected by tightening the tread 5<1> of the second train keeping members 10, 12 in engagement. To effect reversed driving, the sleeve 8 is still driven and the clutch 10 is moved to engage the toothed periphery of ring 13<1>, which rotates constantly in the reversed direction. The tread 6, Fig. 5, has a doubly coned periphery and the tightening rings 13, 13<1> are drawn together by screws 14. The clutch 10 and the tightening rings 7 are operated by levers external to casing 31.

Abstract: 1317161 Ultrasonic inspection devices; ultrasonic probes AUTOMATION INDUSTRIES Inc 1 July 1970 [30 July 1969] 31998/70 Addition to 1312807 Headings H4D and H4J A search unit for ultrasonic testing of a workpiece comprises a first transducer operable to induce eddy current fields in the workpiece, and a second transducer operable to detect acoustical vibrations of the workpiece caused-by the eddy current fields, the second transducer including a transducer element positioned over, and spaced from, a raised portion of a reflective backing member surface. In the Fig. 2 embodiment the first transducer comprises a coil 91 on a core 87 having a bore 90 through which sound waves from the workpiece reach the second transducer. The second transducer is a piezoelectric wafer 49 suspended by two orthogonal resilient strips (e.g. of rubber) from four posts 46, 48 (and 50, 52, Fig. 4, not shown) embedded in a plastic or epoxy insert 42 in the search unit housing 40, 86. Wafer 49 is arranged between two wave reflectors spaced “-wavelength apart, in order to minimize standing wave effects caused by sound reflection at the workpiece surface. One of the reflectors is formed by the lower face of insert 42, which has a central boss 44 for restricting the space behind wafer 49 and so increasing the sound pressure acting on wafer 49. Flaws in or thickness variations of a workpiece (e.g. honeycomb material, particle board or a plywood structure) are detected by observing on an oscilloscope changes in the travel time of the sound waves to the second transducer as the search unit is moved over the workpiece. In a modified search unit the two transducers are arranged side-byside (Fig. 9, not shown) instead of one above the other.

Abstract: 911,384. Stuffing-box substitutes. SULZER FRERES S.A. Sept. 6, 1961 [Sept. 7, 1960], No. 32036/61. Class 122 (5). A rotary gas compressor or turbine shaft 2 mounted in bearings 3, 4 fed with lubricant supplied through a circulating system is sealed by means of lubricant which is introduced into an annular pressure chamber 6 surrounding the shaft at a pressure higher than that on the gas side of the chamber and which flows via a throttle 7 into a duct 8 from which it is discharged by means of a positive displacement pump 10, the capacity of which is such that, simultaneously with the lubricant, a certain quantity of gas is drawn from the machine interior into the duct 8 through a narrow passage 12, the lubricant-gas mixture being pumped into a separator 12<SP>1</SP> where it is separated into its constituents. The duct 8 is surrounded by an inspection chamber 13 which is connected to the interior of the machine through a labyrinth packing 14. The lubricant as it flows from the throttle 7 may be flung into the duct 8 by means of a flange or a flinger ring on the shaft 2. Oil, which constitutes the lubricant, is fed to the chamber 6 from a reservoir 15 by means of a conduit 23 leading through a pump 24, a cooler 25 and a filter 26. The bearings are lubricated from a branch 27 fitted with a throttle 28 and the oil from the bearing housing 9 is returned to the reservoir 15 through a conduit 22. The oil pressure in the conduit 23 is kept constant by a relief valve 33 and is maintained above that on the gas side of the chamber 6 by means of a pressure regulator 29. A mixture regulating device 31 adjusts the amount of gas delivered to the pump 10 by allowing oil to be fed directly to the pump. The separator 12<SP>1</SP> is of the cyclone type provided respectively with gas and oil conduits 16, 18. A gas conduit 21 fitted with an adsorption filter 20 connects the reservoir 15 to a place, e.g. a gas receiver, in the path of flow of the gas. Alternatively, the gas is led directly from the cyclone into the flow path and the reservoir 15 is connected to atmosphere.

Abstract: 368,358. Tents. BUSHNELL, F. B., Arnehurst, Marsh Lane, Taplow, Buckinghamshire. Oct. 27, 1930, No. 32266. [Class 20 (i).] A tent, preferably rectangular or oval in plan, is so constructed that at least one wall or face is vertically " bent " when the tent is erected. In the form shown, a rectangular tent 11, Figs. 1, 2, and 3, is supported at the peak 12 by a slanting pole 13. The pole is supported by a guy-rope 14 arranged in the same vertical plane as the pole. The face 18 of the tent comprises the entrance and two triangular portions or walls 19, 20 extending to the ground and bounded respectively by tapes 16a, 33a and 17a, 34a. These walls are bent respectively about tapes 23, 24 which extend from opposite lower corners of the face 18 and pass over the guy-rope 14 at 12a. As shown in plan, Fig. 3, these tapes are bent by the stretched canvas. The canvas above the tapes 23, 24 and between the tapes 33a, 34a, constitutes an overhanging porch. The entrance to the tent is normally closed by laterally-disposed lower parts 25, 26 of the walls 19, 20, and these parts may be folded back about the tapes 23, 24, or about the tapes 33a, 34a. In order that the entrance may be completely closed, the overlapping parts 25, 26 are each adapted to be secured to the opposite wall at the points 29, 30. The opening 27 above the flaps may be closed by a flap 28. The peak 12 of the tent may be raised by moving the base of the pole 13 towards the centre of the tent, the toggle-like construction of the front face 18 permitting the whole structure to pivot slightly about the rear edge. Such pivoting movement is facilitated by metal links 37 bv which the canvas is secured to the tent pegs. In a modification, Figs. 4 and 5 (not shown), the tent pole is supported by two guyropes. The Provisional Specification also states that the links 37 may be secured to rings which are secured to a doubled-over portion of the canvas.
